Yes! were the incorrect data and FTP generated the error. I do not work in the admin panel with File Zilla worked I did not understand why. I tried to fix htaccess file as written here on the forum but I have not solved
ftp I recorded in Cpanel does not work inside the administration panel to update or load the plugin. I've created one with the same data but the installation still does not work, tells me that this ftp does not have permissions to overwrite the file.
